摘要
建立了染发剂中22种染料成分的高效液相色谱测定方法。使用Discovery?RP-Amide?C16柱(250mm×4.6mm,5μm),以乙腈-0.025mol/L磷酸盐缓冲液(pH6.0,含0.1%的庚烷磺酸钠离子对试剂)为流动相,流速为1.0mL/min;使用二极管阵列检测器(DAD),检测波长为260nm和280nm,柱温为25℃。该方法除了对低浓度的甲苯-2,5-二胺硫酸盐、2-甲基雷锁辛和N,N-二乙基甲苯-2,5-二胺HCl外,对其他各组分的含量测定值的相对标准偏差(RSD)均小于10%,加标回收率为77.6%~122.8%。该方法简便、准确、快速,适于氧化型染发剂中染料成分的检测。
A high performance liquid chromatographic(HPLC)method was developed for the determination of 22 components in hair dyes.The target analytes were separated on an amide bonded C16 silica column(250 mm×4.6 mm,5 μm),employing acetonitrile-0.025 mol/L phosphate buffer(pH 6.0)containing 0.1% 1-heptanesulfonic acid sodium salt as the mobile phase and detected by a photodiode array detector(DAD)with the detection wavelengths of 260 nm and 280 nm.The flow rate was 1.0 mL/min and the column temperature was 25 ℃.The linear range was from 10 mg/L to 500 mg/L with good relationship.The relative standard deviations were less than 10%(except toluene-2,5-diamine sulfate,2-methylresorcinol,N,N-diethyltoluene-2,5-diamine HCl at low concentrations)and the recoveries were from 77.6% to 122.8%.The method is simple,rapid and accurate,and is suitable for the analysis of various hair dyes.
